There is a whole field, that looks a bit like religion to me, about how to test right.

I can tell you from experience that testing is a tool that can give confidence. There are a few new tools that can help. Mutation testing is one I know that can find bad tests.

Integration tests can help find the most egregious errors that make your application crash.

Not every getter needs a test but using unit tests while developing a feature can even save time because you don’t have to start the app and get to the point where the change happens and test by hand.

A review can find some errors but human brains are not compilers it is hard to miss errors and the more you add to a review the easier it can get lost. The reviews can mostly help make sure that the code is more in line with the times style and that more than one person knows about the changes.

You can’t find all mistakes all the time. That’s why it is very important to have a strategy to avert the worse and revert errors. If you develop a web app: backups, rolling deployments, revert procedures. And make sure everyone know how and try it at least once. These procedures can fail. Refine them trough failure.

That is my experience from working in the field for a while. No tests is bad. Too many tests is a hassle. There will always be errors. Be prepared.

An adequate test coverage should help you with these kinds of errors. Your tests should at least somehow fail if you make something incompatible. Also using the tools of your IDE will help you with refactoring.

PrusaSlicer. I like the settings better. It’s a good slicer.

Do you need to switch? I thought openstack had connectors to use VMware as hypervisor. So just stock the openstack on top of your current stack.

I used to name all my devices and servers after old timey womens names but I gut lazy. Now they are named mostly by function.

A few tips that made my prints much better:

• Check if your rollers are tight enough. None of the axes should wobble if you pull on them
• Use a PEI sheet for printing
• Clean the PEI Sheet with Soap and Water at least once
• Clean with IPA after every print
• Don’t touch the print bed. The oil on your skin really doesn’t help with sticking.
• Get yourself a metal feeler gauge with 0.2mm. Level your bed heat nozzel and bed to your normal print temp an then move the nozzel 0.2 mm above the bed. Adjust your Z Offset until you can get the metal gauge undr the nozzle but still feel it touching. that should be your perfect height
• If you still have problems try all the steps here one after another: https://teachingtechyt.github.io/calibration.html

I used to have a lot of problems with parts lifting up or my prints being unclean but since I did this my prints look great and stick to the bed.

For me that looks like slight overextrusion of the top layers. The first few layers are also slightly squished out. The Calibration Cube is a very extreme example. Before you start adjusting I’d print something more natural and if you don’t like that you can go through this: https://teachingtechyt.github.io/calibration.html

I really like that the https://www.ntppool.org project exists for that purpose now.

You mean like centralizing the fediverse? Who hosts the hub? Who maintains it? In which country? Who pays for it?
